The new payment method would rely on Amazon’s contactless payment service called Amazon One. If you haven’t used it before, you will be able to sign up at a participating Panera location. An Amazon’s scanning device will capture small features of your palm, such as veins, wrinkles and creases as you hover your hand over it, and turn them into a ‘palm signature.’ This will be encrypted and sent to a cloud server run by Amazon, where it will be linked to the card you used at the sign-up.

Because your palm print cannot be changed — again, we’re not going to go into the wild stuff — there is literally nothing you can do if it is compromised. So you have to put all your trust in the company processing and storing your palm signature not to leak or misuse it, for example by sharing it with third parties such as law enforcement and advertisers. And if that company is Amazon, a big tech heavyweight that has a checkered history when it comes to privacy and security, then you might want to think twice.

Interesting. Biometrics returns. I guess your threat model would be rather small, you're not going to lose your hand, are you ?
